74HC374; 74HCT374 Octal D-type flip-flop; positive edge-trigger; 3-state Rev. 3 — 20 February 2018 1 Product data sheet General description The 74HC374; 74HCT374 is an octal positive-edge triggered D-type flip-flop with 3‑state outputs. The device features a clock (CP) and output enable (OE) inputs. The flip‑flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops. Inputs also include clamp diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. The 74HCT374 features reduced input threshold levels to allow interfacing to TTL logic levels. 2 Features and benefits • Input levels: – For 74HC374: CMOS level – For 74HCT374: TTL level • Octal bus interface • Non-inverting 3-state outputs • 8-bit positive, edge-triggered register • Common 3-state output enable input • Independent register and 3-state buffer operation • Complies with JEDEC standard no. 7 A • ESD protection: – HBM JESD22-A114F exceeds 2000 V – MM JESD22-A115-A exceeds 200 V • Specified from -40 °C to +85 °C and -40 °C to +125 °C 74HC374; 74HCT374 Nexperia Octal D-type flip-flop; positive edge-trigger; 3-state 3 Ordering information Table 1. Ordering information Type number Package 74HC374D Temperature range Name Description Version −40 °C to +125 °C SO20 plastic small outline package; 20 leads; body width 7.5 mm SOT163-1 −40 °C to +125 °C SSOP20 plastic shrink small outline package; 20 leads; body width 5.3 mm SOT339-1 −40 °C to +125 °C TSSOP20 plastic thin shrink small outline package; 20 leads; body width 4.4 mm SOT360-1 74HCT374D 74HC374DB 74HCT374DB 74HC374PW 74HCT374PW 4 Functional diagram 1 EN 11 11 3 4 7 8 13 14 17 18 3 CP D0 Q0 D1 Q1 D2 Q2 D3 Q3 D4 Q4 D5 Q5 D6 Q6 D7 Q7 OE 1 2 5 D0 Q0 2 4 D1 Q1 5 7 D2 Q2 6 5 8 D3 Q3 9 13 D4 14 D5 17 D6 Q6 16 18 D7 Q7 19 6 7 6 9 8 9 12 13 12 14 15 17 16 11 CP 18 19 1 OE 15 16 19 mna891 D0 3 2 1D 4 D2 D CP Q D3 D CP FF1 3-STATE OUTPUTS Q Q5 15 CP FF2 Q D5 D CP FF3 Figure 3. Functional diagram D4 D Q4 12 mna892 Figure 2. IEC logic symbol D1 Q FF1 to FF8 mna196 Figure 1. Logic symbol D C1 Q D CP FF4 D6 Q D CP FF5 D7 Q D CP FF6 Q CP FF7 FF8 CP OE Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 mna893 Figure 4. Logic diagram 74HC_HCT374 Product data sheet All information provided in this document is subject to legal disclaimers.
